A remark on conditions that a diffusion in the natural scale is a martingale

Research output: Contribution to journal › Article › peer-review

Abstract

We consider a diffusion processes {X_t} on an interval in the natural scale. Some results are known under which {X_t} is a martingale, and we give simple and analytic proofs for them.
